The equipment at Littleworth Lane was set alight last month, forcing Barnsley Council to remove its contents for the safety of users.
Wendy Lowder, executive director for communities, said: “It’s very disappointing to hear that the playground at Littleworth Lane was subject to yet more vandalism.
“Sadly, this is not the first time vandalism has seen the play area needing removals and repairs in the last two years, with numerous incidents of small fires and other damage.
“We don’t tolerate this sort of behaviour in our borough, and we’re joining forces with partners at South Yorkshire Police and South Yorkshire Fire and Rescue to identify the offender.
“In the meantime, we will have to remove the play equipment for safety reasons as the damage is beyond repair, costing £20,000 to replace.
